Qalvin is Quarq’s app for power meter zeroing, diagnostics, firmware upgrades and calibration. We originally developed Qalvin so first and second generation power meters could be calibrated in the field. OmniCal™ removes the need for recalibration, but Qalvin remains indispensable for shops, mechanics, teams and athletes, and anyone seeking the latest firmware version or enhanced information for their power meter.
1. Qalvin for Windows and Mac requires an ANTUSB2 or ANTUSB-m stick. Most ANT+™ USB sticks that come with Garmin fitness watches are compatible with Qalvin. Note: Qalvin and the Garmin ANT Agent™ cannot use an ANT+ USB stick at the same time. Close one program to use the other.
2. First and second generation power meters include the Quarq CinQo, CinQo Saturn, Saturn2 and Quattro MTB; SRAM S975 and S2275 MTB.
